West Ham United have been told to up their offer for Everton striker Yakubu Aiyegbeni.

The Daily Mail says Everton have rejected an improved £7million offer from West Ham for striker Yakubu.

West Ham owner David Sullivan is determined to give new manager Avram Grant a proven goalscorer and sees the 27-year-old Nigerian as the ideal man.

Although Yakubu struggled with six goals last term, he was coming back from a serious achilles injury and Grant believes he can recover his sharpness through the World Cup and extra pre-season training.
